Embodiment Construction

[0028] The implementation of the percutaneous wireless charging device with multiple closed-loop temperature control and protection functions for implantable medical instruments of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] figure 1 It is a schematic diagram of implanting rechargeable batteries and titanium shell temperature protection. Implanted rechargeable batteries with elevated temperatures or elevated temperatures in the titanium case may pose a risk of thermal injury to the patient. When the temperature of the implanted medical device is higher than the set target temperature, the temperature protection function of the implanted rechargeable battery and titanium shell will be triggered, the wireless charging circuit will be forcibly disconnected, and corresponding reminders will be given to the patient to ensure its thermal safety .

[0030] The temperature sampling resistor 31 of the titanium shell 11...

Abstract

The invention provides a percutaneous wireless charging device with a multi-closed-loop temperature control and protection function for implantable medical devices. Thermal safety and high energy transfer efficiency of the percutaneous wireless charging device in different charging stages and at different alignment positions are realized through multi-closed-loop temperature control and highest temperature protection design. By controlling the temperature with high steady-state accuracy, stable charging in short charging time is realized, and thermal safety in the charging process is ensured.

Description

technical field [0001] The invention relates to a percutaneous wireless charging device with multiple closed-loop temperature control and protection functions for implantable medical instruments, belonging to the technical field of implantable medical instruments. Background technique [0002] In recent years, with the development of wireless technology and lithium rechargeable battery technology, rechargeable implantable medical instrument products have become the mainstream trend of development. When an implantable medical device is implanted into the patient's body, it needs to adopt a percutaneous wireless charging method. This charging method is generally based on the principle of electromagnetic coupling, and uses electromagnetic fields to penetrate the human skin to transmit energy to the implanted medical device. [0003] Implantable medical instruments are generally sealed with biocompatible metal titanium. Due to the eddy current effect of the titanium shell during...
